Learning Path For Java Developer

Updated: Aug 13, 2022

Java is one of the world's most popular programming languages. More than nine million developers consider Java to be their first language when it comes to its popularity. As a result, Java's global popularity is undeniable. In 1995, Java was released as a general-purpose, object-oriented programming language. Although it was first launched almost 25 years ago, Java remains one of the top three programming languages.

Java is one of the most popular programming languages in today's world because it can be used to create highly scalable, light and quick programmes that can be used for many reasons.

Despite competition from new languages, the demand for Java Developers remains robust. Depending on who you ask, Java is one of the most in-demand programming languages on the employment market. Java has long been the most popular programming language, from learning your first programming language to developing highly scalable systems. But, first and foremost, who is a Java Developer?

Java Developer

A Java developer, often known as a coder, works with software engineers to integrate Java into corporate software, applications, and websites. During the application development cycle, a Java developer is responsible for various tasks. The following are some of their main responsibilities:

  • Create, deploy, and maintain a Java application

  • Analyzing, testing, creating, and debugging software

  • Make stipulations out of requirements.

  • Recommendations for improvements to an existing Java application

  • Create technical designs for app development, among other things.

In Malaysia, the average Java developer income is RM 78,192 per year. Depending on parameters such as experience level, region, company profile, and so on. It is now evident why one should pursue a career as a Java developer. Now comes the question of where to begin. Where do I begin? What are the issues that should be covered? Plus, a lot more. Do you need to study all of the principles from a book, go through some online courses, or learn Java Development by working on some projects? Let's go over all of this in-depth in this essay.


Learning Path

Begin by reading the Java Overview. Read several blogs about Java Development and do some studies about Java Development. For example, read articles on Introduction to Java, History of Java, and themes such as Is it Worth It to Become a Java Developer in 2022, etc., and prepare your mind to begin your Java Development journey. Make yourself inspired to study Java Development and create some cool Java projects. Do it regularly, and start learning new concepts one by one. Before you begin your adventure, it might be beneficial to attend some Java Development seminars or conferences.

Core Java

The first thing you should learn in this Java Developer roadmap is Core Java. As a result, you must study the following important subjects in core Java:

  • Java 8

  • Data Types and Variables

  • String Class

  • Conditional Statements and Loops

  • OOPs Concept in Depth

  • Features and Architecture

  • Operator and Expressions

  • Multithreading

  • JAVA IO Streams

  • Collection Framework

Advanced Java

After you've mastered Core Java, you'll need to brush up on Advanced Java principles. The following topics are covered in this Advanced Java course.

  • Design Pattern

  • JVM

  • Concurrent Programming

  • Garbage Collection

  • Best Practice and Code Structure

  • Threads

  • Servlet and JSP's

You don't need to understand anything in-depth in advanced Java; all you need to know is how everything above works. And you may read about these things and incorporate them into your project anytime you're working on them.


You should be able to code java applications once you've mastered the fundamentals and advanced features of the language. As a result, you should be familiar with any of the following IDEs.

  • IntelliJ IDEA

  • Eclipse

  • Spring Tool Suite

  • VS Code

To improve your workflow and efficiency when developing applications, you should be aware of the many shortcuts for your IDE, whichever one you like.

Build Tools

Now you should be able to build all of your Java code. As a result, you must know the various build tools to construct your Java project. The following are some of the fantastic tools you may utilize to create your Java project:

  • Maven

  • Gradle

  • Ant


It's time to launch your web application after you've finished developing it. So, because you'll be deploying your web application on a server, you'll need to be familiar with at least one server. The most extensively used server is Tomcat. Apart from that, JBOSS is used in a variety of settings.

  • Tomcat

  • WebSphere

  • Jetty

  • Weblogic



As data storage is critical for developing a Java program, a database is essential. As a result, if you work in a company, you will have to work with databases. To perform various activities on a database, you must construct queries. So, here are some of the topics you'll need to learn:

  • SQL

    • ACID

    • Joins

    • Indexes

    • Constraints

  • Advanced SQL

    • Procedures

    • Packages

    • Functions

    • DBA

  • NoSQL

    • MongoDB

  • ORM (Object-relational mapping)Framework

    • JPA (Java Persistence API)

    • Hibernate

    • iBatis

    • Spring Data JPA


Testing is an essential part of your development process. As a result, you must understand how to test your Java program to reduce errors and increase efficiency.

  • Unit Testing

  • Junit

  • Mockito

  • Integration Testing

  • Debugging Code (Must know)


In Java, there are a variety of logging libraries to choose from. As a result, whenever you construct a Java application, you should keep track of any problems or files to learn more about what's going on in the system. Any of the following must be known to you. Libraries for logging:

  • Log4j

  • Log4j2

  • Logback


In Java, there are numerous frameworks to choose from. These frameworks promote easier debugging, a large amount of code reuse, increased code efficiency, and reduced overall development time. Some of the Java Frameworks that you can learn are listed below:

  • Spring

  • Spring Boot

  • Hibernate

  • JSF

  • GWT

  • Micronaut
